FAQ:
1. What is rock drilling?
Rock drilling tools include those used for oil and natural gas exploration, mining, construction, and all other industrial operations that need to excavate or drill through natural rocks, concrete, and masonry.
2. What is the weakest rock in the world?
Loess is formed from fine (small) grained, windblown sediment in glacier or desert areas. Loess is made of mostly silt but may also have some small amounts of sand and clay. The major mineral present is quartz with minor amounts of feldspar, calcite, dolomite, and clay.
3. What is DTH bit?
Down-the-hole (DTH) hammer bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill hammer bits are designed with a splined drive for rotating the bit in the ground.
